What term refers to sewing that repairs a worn or torn hole?

The term that refers to sewing that repairs a worn or torn hole is "mend." This word specifically denotes the act of repairing something that is damaged or broken, particularly in the context of fabric or clothing. When you mend, you are rejoining pieces or reinforcing an area to restore it to a usable state. This process is often associated with patching holes or fixing seams, making it the most fitting choice for the question posed.

In contrast, "incubate" relates to maintaining conditions favorable for development, often used in biological contexts, such as hatching eggs or developing cultures. "Insinuate" means to suggest or hint at something in an indirect way, which does not align with the concept of sewing or repairing. "Inveterate" describes a habit or activity that is long-established and unlikely to change, which also does not pertain to the idea of repairing something like clothing. Therefore, "mend" is the most appropriate and precise term in this context.
